Abstract

Two new compounds, methyl 3-chloro-6-hydroxy-2-(4-hydroxy-2-methoxy-6-methylphenoxy)-4-methoxybenzoate (1) and (2S,5′R,E)-7-hydroxy-4,6-dimethoxy-2-(1-methoxy-3-oxo-5-methylhex-1-enyl)-benzofuran-3(2H)-one (2), together with four known compounds, griseofulvin (3), dechlorogriseofulvin (4), bostrycin (5), and deoxybostrycin (6), were isolated from the marine endophytic fungus Nigrospora sp. (No. 1403) collected from the South China Sea. The structures were elucidated by spectroscopic methods, 1D, 2D NMR, and HREIMS. Compounds 5 and 6 showed moderate antitumor and moderate antimicrobial activity.
